Finally some good winter weather and nice wind. Episode 24 of Open Source Trickkites features the Matrix Ultralight. Original design by Alberto Cavati and Mario Di Biase from Italy. I created a different layout for my Matrix and used a laser cutting machine to make the sail. Very convenient. The Matrix is a very capable kite and a lot of fun to fly. Build one!
